Question

Very little info about Stem Tuber.

Answer 1

a stem tuber is formed due to thickening of rhizomes. They tend to form at the sides of the parent plant and are most often located near the soil surface.

Answer 2

Hello friend! I am glad to help you, here is the answer.

Stem Tuber ( eg. Potato):
>> It is an underground modification of stem.
>> The tips of the underground  branches of potato plant swell up due to storage of food material.
>> A tuber has distinct nodes called 'eyes'.
>> Each eye bears an axillary bud and a scale leaf. 
>> Each axillary bud can grow into a new plant.
>> Stem tubers function as organs of perennation, storage of food and vegetative reproduction.


I hope this will help you. Thank you.
